. METAL FRAME Specification of Letters Patent.

Patented Oct. 13, 1908.

To all whom it may concern:

Be it known that we, EMIL JOSEPH H0011- ULE and J osnrn ALFRED BOUSQUET, citizens of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Metal Frames, of which the following is a specification.

This invention relates to metal frames for screen doors and windows, the object being to provide a frame which is so constructed that it can be readily made to fit any size door or window.

Another object of our invention is to provide a screen which is provided with biting spurs ada ted to engage the wire net when arranged etween the bars of the screen so as to hold it taut.

A further object of our invention is to provide a frame which is exceedingly'simple and cheap in construction and one which is provided with double vertical and horizontal strips which are connected together at their corners by angled irons so as to hold the frame rigid.

With these objects in view, the invention consists in the novel features of construction, combination and arrangement of parts, hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this specification :Figure 1 is a front view of our improved frame showing it arranged in a window. Fig. 2 is a detail rear view of the same. Fig. 3 is a section taken on line 3-3 of Fig. 2. Fig. 4 is a detail rear view showing one of the angle-irons removed. Fig. 5 is a section taken on the line 55 of Fig. 4, the angle iron being shown in elevation. Fig. 6 is a perspective view of a portion of our improved frame showing the members separated.

In the drawings A indicates a metal frame which is formed of inner and outer vertical side strips B and O and inner and outer horizontal strips D and E which are connected together at their corners by angle-irons F and G. The outer vertical stri s B are provided with outer flanged edges l3 and inner vertical strips 0 are provided with inner flanged edges C so when united the edges form a channel in which the angle-iron G is adapted to fit, the angle iron F being provided with a flanged outer edge F which fits over the flanges of the outer strips, the horizontal strips being also formed with flanges D E and are provided with spaced openings which register with spaced openings formed in the angled irons, through which rivets H are adapted to pass and secure the strips together. The vertical strips are also provided with openings through which rivets pass for securing the same together.

The outside horizontal strips extend up against the vertical side flanges of the angleirons F and the inside vertical stri s rest on the horizontal flanges of the angle -irons F, the flanges 0 being cut away the width of the angle-irons, so that the end of the inside horizontal strips will rest flush against the same forming a tight joint. The inside horizontal and vertical strips are provided with spurs I which are formed by dies and extend inwardly and are adapted to engage the wire netting J when arranged between the inner and outer strips, so as to revent the same from moving, the strips eing secured together by rivets K which are spaced about a half-inch apart.

It will be seen that by removing the inner angle-irons and inner strips the netting can be readily detached and a new iece inserted, and that by forming the vertica and horizontal strips of diflerent lengths they can be geadily assembled to fit any size window or oor.

Having thus fully described our invention, I

what we claim as new and desire to secure by Letters Patent is 1. A frame comprising vertical and horizontal inner and outer strips, the outer strips being flanged on the outer edge and the inner on the inner edge to form a groove, and angle irons secured in the grooves at the corners, and means for locking said strips and angle irons together.

2. A metal frame formed of inner and outer strips having flanged edges to form a groove, the inner strips being provided with biting spurs, outer angle-irons arranged over the corners of said frame, an inner angle-iron arranged in the groove formed by said strips opposite said outer angle-irons, said strips and angle-irons being secured together by rivets.

3. A metal frame formed of inner and outer vertical and horizontal strips, the inner strips being provided with blting spurs adapted to engage the edges of the Wire net I ranged over the ends of the inner strips, said When arranged in said frame, the inner strips angle-irons being secured together by rivets.

being provided with flanged inner edges and EMJL JOSEPH HOGHUMI. the outer strips Wlth flanged outer edges, sard JOSEPH A LINKED BQUs UE'P, strips being secured together by rlvets, fitnes'ses:
